Fig. 12 is a sectional view on the line |2-I2 35` of Fig. 11.

Fig. 13 shows the devices controlling movement of the pinion El intomesh with the pinion 62.

The seconds hand spindle l, the minutes hand spindle 2, and the hourhand spindle 3 are con- 40 centric and of different lengths. The secondsspindle I is at the center and extends farther to the front than thespindles 2 an-d 3, the minutes spindle extending farther to the frontthan the hour spindle 3. The three spindles rotate about 45 the sameaxis and the hands (not shown) attached to the front end of saidspindles cooperate with the same dial. All of these spindles extendforwardly beyond the front frame 4 of the clock.

The seconds spindle I exten-ds rearwardly 50 through the rear frame ofthe clock and is rotated in a clockwise direction (Fig. l) by anappropriately mounted and connected motor (not shown). A pinion 5 isrigid with the spindle l and with a gear B, so that the pinion 5 and the55 gear 5 are rotated by the spindle I. The pinion 5 meshes with a gear'I attached to a rotary shaft 8 having rigid therewith a pinion 9 (Fig.2) which meshes permanently with a gear I9 mounted on the spindle 2. Theratio of this gearing is such that the seconds spindle I is rotated acomplete revolution during each minute and the spindle 2 is rotated onlythe distance of one minute with respect to the dial during each completerevolution of the spindle I.

The spindle 2 has attached thereto a pinion II (Fig. l) which rotatesthe spindle 3 through a chain of reduction gearing comprising a gear i2meshing with the pinion II an-d attached to and rotating a pinion I3meshing with a gear I4 attached to the spindle 3. The ratio of thisspeed reduction gearing is such that the spindle 3 is turned thedistance of one hour with respect to the clock dial for each completerevolution of the spindle 2.

A plate I5 (Figs. '7, 8 and 9) is attached to the spindle 2 and hasprojecting from one side iour pins I9, Il, I8 and I9. These pins arediierent radial distances from the axis of the spindle 2, being ofgradually increasing distances from said axis from the pin i6, which isclosest to the axis, to the pin I9, which is farthest from the axis.These pins control, in cooperation with other elements yet to bedescribed, the operation of the chiming devices for the quarter-hour,the halfhour, the three-quarters of an hour, and the hour, respectively.A lever 29 mounted on a pivot 2| is formed with a cam 22 against whichthe pins I6, I7, I8 and I9 operate successively. A spring 23 actuatesthe lever 29 to hold the pointed cam 22 in engagement with therespective pins I6, II, I8 and E9. As shown in Fig. 8, which is lookingfrom the rear toward the front of the clock, the series of pins I6, II,i8 and I9 are rotated in a counterclockwise direction and willsuccessively move the lever 23 downwardly until the respective pins passbeyond the sharp point of the cam 22 and release the lever so that thespring 23 can move the lever upwardly again into contact with the nextpin for operation thereby. When the lever 2i] is moved downwardly by therespective pins, it engages and pushes downwardly a pin 24 whichprojects through a slot 25 formed in the front frame plate 4, The pin 24is supported by and projects rearwardly from a lever 26 mounted on apivot 21 supported at the front of the frame plate 4 and actuatedupwardly by a spring 28. When the lever 26 is pushed downwardly by thelever 20, a pin 29 on the free end of said lever is disengaged from atooth 39 formed on a rack sector 3l supported by an arm 32 mounted on apivot 33. The rack sector 3I is formed with a pair of teeth 34corresponding to the pin i6; with a pair of teeth 35 on a longer radiusfrom the axis of the pivot 33 than the teeth 34 for the pin I'I; with apair of teeth 36 on a longer radius than the teeth 35 for the pin I8;and with a pair of teeth 3'I on a still longer radius than the teeth 36for the pin I9.

Therefore, the element I5 with the pins I9, Il, I8 and I9 supported andoperated thereby constitute a device or means for releasing the pin 29from the shoulder 30. When the pin I6 releases the pin 29 from theshoulder 39, the rack 3I will drop until the first or lowest tooth 35engages the pin 29 to support the rack. When the pin I1 disengages thepin 29 from the shoulder 39, the rack 3I will drop until the lowesttooth 36 engages the pin 29. When the pin I 8 operates to disengage thepin 29 from the shoulder 3U, the rack 3| will drop until the rst orlowest tooth 31 engages the pin 29 to stop further movement of the rack.When the pin I9 operates to disengage the pin 23 from the shoulder 39,the rack 3i will drop until the arm 38 engages the snail element 39rigidly attached to the hour spindle 3 The said arm 38 is rigid with therack arm 32. As shown, the snail element is formed with twelveperipheral steps or segments corresponding to the hours, and atdifferent radial distances from the axis of the spindle 3. The snailelement is familiar in clocks.

Downward movement of the rack 3i by action of the pin i5 as describedconditions the chiming mechanism for operation of the selected chiming'elements at the rst quarter-hour; downward movement of said rack 3! byaction of the pin I'l as described conditions the chiining mechanism foroperation of the selected chiming elements at the half-hour, preferablytwice the number oi operations at the quarter-hour; downward movement ofsaid rack 3l by action of the pin I8 as described conditions the chimingmechanism for operation of the selected chiming elements at thethree-quarter hour as often as desired; and downward movement of saidrack 3i by action of the pin I9 as described conditions the chimingmechanism for operation of the selected chiming elements any desirednumber of times at the hour.

The plate I5 has projecting therefrom four equally spaced pins d4 on theside opposite from the pins i6, i'i, etc. (Figs. '7 and 9). A lever 45is mounted on a pivot 35 and is actuated in one direction and against apin 5"] by a spring 48. The upper end 39 of the lever 45 is in the pathof movement of the pins i4 so that, as the minutes spindle 2 rotates,one of the pins 24 will engage and move the lever 45 each quarter-hour.At the proper times, the respective pins 44 escape from the end (i9 ofthe lever 45, whereupon the spring 48 quickly moves said lever 45 towardits starting position. An arm 59 is pivotally supported by the lever 45and has in its underside a notch 5I adapted to be engaged with anddisengaged from a pin 52 projecting from a support 53 mounted forswinging movements on a rod 54. The arm 59 is provided with a rebent endportion 55 extending laterally in iront of the plate I in position to beengaged by a lnger 55 rigid witn the rack 3|. When the rack 3i is in itsunoperated position with the pin 29 engaging the shoulder 39, the iinger55 supports the arm 59, so that the notch 5I is above and out ofengagement with the pin 52. When the rack 3l is moved downwardly asdescribed, the nger 55 moves downwardly with said rack and permits thearm 59 to drop, so that the notch 5i will receive and engage the pin 52when the lever 45 is moved forwardly by any one of the pins M... Then,while the notch 5I is in engagement with the pin 52, and after the pin33 releases the lever 45, the spring 43 moves said lever 45 toward itsstarting position, and this movement of said lever 45 causes the arm 59to swing the support 53 in opposition to a spring 57.

IThe gear 6 which is attached to the seconds spindle I is in permanentmesh with a pinion 53 (Figs. 2 and 5) attached to a spindle 59. A gear60 is also attached to and rotated by the spindle 59 and is in permanentmesh with a pinion 5I rotatively carried by the swinging support 53.When the support 53 is moved by the arm 59 as described, the pinion 3iis moved into mesh with a pinion 62. "le movement of the pinion EI byoperation of the swinging support 53 by the arm 50 is from the positionshown in Fig. 2 to the position shown in Fig. 5. When the arm 50 isdisengaged from the pin 52, the spring 51 immediately vmoves the support53 and thereby the pinion 6| from the position shown in Fig. 5 to theposition shown in Fig. 2, in which latter position the pinion 6| is outof mesh with the pinion 62.

The pinion 62 is attached to a rotary spindle 63 and is in permanentmesh with a pinion 64. The pinions 62 and 64 are rotatively carried by aswinging support 65 pivoted on the spindle 63. A spring 66 connectedwith the support 65 moves said support to the position shown in Fig. 3,but said support is operative to move the pinion 64 into and out of meshwith a gear 61 attached to a rotary shaft 68. The support 65 has a pin69 projecting across a cam 16 attached to and rotated by the minutesspindle 2 so that said cam will operate the swinging support 65 to movethe pinion 64 into mesh with the gear 61 and thereby rotate said gear 61when, and only when, the pinion 6| is in mesh with the pinion 62.

From the foregoing, it is apparent that the plate I5, which is mountedon and operated by the minutes spindle 2, performs the function ofconditioning for operation the operating mechanism for the chimingdevices, and also functions to operate the lever 45 which controls themechanism for rotating the spindle 68. This spindle 68 is an essentialpart of the operating mechanism for the chiming devices 46, 4|, 42 and43. The spindle 68, which is rotated by the gear 61 as described, hasattached thereto a pair of discs 1| and 12. An annular series of pins 13project from one side of the disc 1| and an annular series of pins 14project from the opposite side of the disc 1|. An annular series of pins15 corresponding to the pins 13 project from one side of the disc 12 andan annular series of pins 16 corresponding to the pins 14 project fromthe opposite side of said disc 12. Each series of pins is in staggeredrelationship with respect to every other series of pins, which is to saythat no series of pins is in alinement with any other series of pins,because said pins are relatively circumferentially spaced. The disc 1|extends between the chiming device parts 46 and 4| while the disc 12extends between the chiming device parts 42 and 43. Therefore, when thespindle 68 is rotated in the direction of the arrow 11 (Figs. 3 and 4)the pins 13 will operate the chiming device 46 intermittently, the pins14 will operate the chiming device 4| intermittently, the pins 15 willoperate the chiming device 42 intermittently, and the pins 16 willoperate the chiming device 43 intermittently, and no two chiming deviceswill be operated at the same time.

When the lever 45 and the train of connections therefrom are operated tomove the pinion 6| into mesh with the pinion 62, a relatively large hub18 engages a relatively large collar 19 rigid on the spindle 63 to limitand stop movement of the support 53 and the connections therefrom to thelever 45. This contact of the hub 18 with the collar 19 does not occuruntil the pinion 6| is in proper mesh with the pinion 62.

An arm 80 projecting from the support 65 supports a pin 8| which extendsacross the disc 1| and, at the end of each hour, engages in a notch 82in said disc. The cam 16 has a definite relationship to the hands of theclock so that, when the minute hand points to 12 on the clock dial atthe end of each hour period, the lowest side of the cam 16 is, as shownin Fig. 3, in engagement with the pin 69. During. the next quarterhour,the cam 10 turns from the position shown in Fig, 3 almost to theposition shown in Fig. 4 and thereby disengages the pin 8| from thenotch 82 simultaneously with the meshing of the pinion 6| with thepinion 62. chimes are operated in the desired sequence to chime thequarter-hour and, immediately after the completion of the chiming of thequarterhour, the pinion 6| is moved out of engagement with the pinion 62and rotation of the discs 1| and 12 is stopped. The cam 16 then rotatesapproximately ninety degrees to the half-hour, the pinion 6| is movedinto mesh with the pinion 62, and the chimes are again operated. Uponthe completion of the half-hour chiming, the pinion 6| is again movedout of mesh with the pinion 62 and rotation of the discs 1| and 12 isstopped. The cam 16 continues to rotate to the threequarter hour point,where the chiming operation is repeated for the three-quarter hour.Continued rotation of the cam 16 brings the low point thereof intocontact with the pin 69, the chimes are operated on the hour and,immediately upon completion of the chiming operation, the pin 8| dropsinto the notch 82 and the pinion 64 is moved out of mesh with the gear61.

At this time, when the pin 8| drops into the notch 82, -the pinion 64 ismoved out of engagement with the gear 61; so that the gear 61 will notbe rotated irrespective of whether the pinion 64 is rotated or not.Simultaneously with the engagement of the pin 8| within the notch 82,the pinion 64 is moved out of mesh with the gear 61 by action of thespring 66 and the arm 56 is moved upwardly out of engagement with thepin 52 by the movement of the rack 3| to its unoperated position inwhich the shoulder 30 is engaged with the pin 29. The pinion 6| isdisengaged from the pinion 62 after each chiming operation; which is tosay that the pinion 6| is disengaged from the pinion 62 after thequarter-hour chiming, after the half-hour chiming, after thethree-quarter hour chiming, and after the chiming at the hour. But thepinion 64 is held in engagement with the gear 61 after the quarter-hourchiming through the hour chiming and until the cam 16 moves to theposition shown in Fig. 3, in which its low point engages the pin 69 topermit operation of the support 65 by the spring 66 to disengage thepinion 64 from the gear 61 and engage the pin 8| in the notch 82 inorder to stop positively rotation of the spindle 68 by the gear 61.

At the hour, after the completion of the chiming the hour is struck by astriker 83 supported on the spindle 84 which also supports the chimingdevices 46, etc. (Figs, 2 and 3). The hour striker 83 is connected by aspring 85 with a lever 86 mounted on the same spindle 84 with thestriker 83. A pin 81 on one arm of the lever 86 projects behind thestriker 83 so that, when the lever 86 is swung upwardly in opposition tothe spring 85, said pin 81 will move the striker 83 upwardly.

One arm of the lever 86 has a pin 88 projecting laterally therefromunder the free end of a lever 89 pivoted on the rod 54. T'he lever 89 isa bell crank lever and has an arm 96 provided with pin and slotconnection 9| with a stud 92 that supports or is coaxial with the pinion64. By reference to Figs. 2 and 3 of the drawings, it is apparent thatswinging movement of the pinion 64 into mesh with the gear 61 will pushdownwardly the free end ol' the lever 89 against the pin 88 which willswing downwardly the adja- Thereupon the "liti cent arm of the .lever 86to a position in which .the free end of the lever 86 is out of the pathof movement of pins 93 on opposite ends of a support 94 attached to androtated by the spindle 63. Therefore, when the pinion 64 is in mesh withthe gear 6l, which it is during all chiming operations, the support 94can rotate with the spindle 63 without operating the lever 86 by thepins S3. But, when the pinion 64 is out of mesh with the gear 6l, asshown in Fig. 3, rotation of the support 94 by the spindle 63 willengage the pins 93 successively and alternately with the lever 86 andwill operate said lever and thereby the hour striker 83 intermittentlyand successively as many times as the respective pins 93 engage andoperate said lever 86.

When the pinion 64 is moved into mesh with the gear 67, the lever 89 ismoved downwardly against the pin 88 and thereby moves the lever 86downwardly. When the lever 86 is held in its downward position by thelever 89, the end of the lever 86 is out of the path of movement of thepins 93 so that the support 94 can rotate freely without operating thestriker 83. Therefore, the striker 83 is held idle during operation ofthe chiming devices and the chiming devices are idle during operation ofthe striker in the embodiment of the invention shown. However, theinvention is not restricted to the use of a separate striker for thehours.

The spindle 63 projects forwardly through and beyond the plate I andsupports two pins 95 adapted to engage alternately with the teeth on therack 3| when said rack is in any of its downward positions and therebyraise the rack step by step a distance of one tooth at a time, the racksliding along the pin 29, until the rack is raised to the position shownin Fig. l, in which the pin 29 engages the shoulder 30.

Even after the arm 58 is disengaged from the pin 52, a pin 96 on thesupport 53 remains in engagement with one of the high points of a cam9'! (Fig. 6) and thereby holds the support V53 approximately in theposition to which it had been moved by the arm 58. However, after thecam 91 has turned about one-quarter of a revolution, a low point of thecam is brought opposite the pin 96, whereupon the spring 51 immediatelyswings the support 53 to its starting or idle position in which thepinion 6I is out oi mesh with the pinion 62.

In the foregoing operations of chiming quarterhours, and then at thehour periods striking the hours after the operation of 'the chimingelements by operation of the striker 83, said striker 83 is operated attwice the speed ofthe operation of any of the chiming elements and, atthe correct speed of operation, vto strike clear notes vto signify thehours.

In these operations, the chiming elements are automatically coordinatedproperly as 'totime of operation with the hands of the clock because thenotch 82 will permit the pin 8! to engage therein only under control of'the cam '10, the low point of which has a definite relationship andadjustment with the minutes hand of the clock. I'term this an automaticcorrection of any possible error that may occur during any hour periodin reference to the time of operation of the chimes with respect to theposition of the minutes hand and therefore with respect to the hour handand the seconds hand of the clock. This is because the notch 82 has adefinite and Xed relationship to the low point of the cam 'I8 (Fig. 3).

As indicated in Fig. 9 of the drawings, the

lever 45 and the cam extension 22 are iiared in such a way as to permitthe pins I6, Il, I8 and I9, and also to permit the pins 44, to operateagainst the respective parts 22 and 49 so that the plate I attached tothe minutes spindle 2 may be rotated in a counter-clockwise direction toset the hands of the clock properly, as may be necessary or desirablewhen the clock requires reverse operation for resetting purposes.

During operation, the spindle I rotates the gearing 5, 1, 9, I8, andthereby #the spindle 2 at proper speed ratios. The spindle 2 rotates theplate I5 and thereby the pins I6, etc. to operate the lever and therebythe lever 26 to permit descending operation of the rack 3| predetermineddistances according to which of the pins I6, I'I, etc. operates thelever 28. Then the lever 45 is operated at proper times by the pins 44and the pinion 6I is meshed successively with the pinion 62, and thepinion 64 is meshed with the gear 61, whereupon the discs 'II and l2 areoperated to operate the chiming devices 48, 4I, 42 and 43 in apredetermined and selected order to produce a musical effect. The camlll, during its rotation against the pin 69, operates the support 65 toraise the pin 8l out of the notch B2 at or immediately before meshing ofthe pinion S4 with the gear 61 so that the gear 67 and thereby the discs1I and 'I2 may rotate freely without resistance by the pin 8|. When thepin 8l is raised to or above the periphery of the disc 'II and becomesengaged on the periphery of said disc 1I, said pin cannot again enterthe notch 82 until said notch 82 has been rotated to position to receivethe pin 8|, notwithstanding the fact that the high point of the camadjacent the arrow (Fig. 3) has passed beyond said pin `69,.v But, whenthe pin 8| is at the notch 82, said pin will enter said notch, thesupport 65 will be operated by the spring 66, the pinion 64 will bedisengaged from the gear 5'! and rotation of the chime operating discs'Il and 'I2 will be stopped.

When the pinion 6I is moved toward the pinion 62, extent of movement ofthe pinion 6I will be stopped by the hub 'I8 engaging against theperiphery of the collar 79 effectively to prevent the teeth on thepinion 6I from abutting against the bottoms of the notches between theteeth on the pinion 62 so that the teeth on said pinions are not movedinto abutting engagement with the bottoms of the spaces between saidteeth. This compensates for any irregularities or tolerances resultingfrom unequal depths of the spaces between the teeth on the respectivepinions and prevents locking of the gearing that might otherwise occur.

From the foregoing, it should be apparent that this clock operating andchiming mechanism attains all of the intended objects and functionsstated at the beginning of this specification or otherwise attributedthereto through the foregoing description. I am aware that themechanisms may be varied within the scope of equivalent limits withoutdeparture from the nature and principle thereof, and do not restrictmyself unnecessarily.
